Ngophuhliso olukhawulezileyo lwesayensi kunye netekhnoloji, itekhnoloji ye-3D ibonakalise ixabiso layo eliqhelekileyo kumasimi amaninzi, ngakumbi kwicandelo lezonyango. Phakathi kwazo, i-Polyteether Ether Ketone (i-Pek), njengezinto ezisebenza kakhulu kwi-Thermoplastic, ivula isahluko esitsha kwishishini lezonyango ngokusetyenziswa kwemodeli ye-FIPICT (i-FDM) ye-SIDRED.
I. Iipropathi kunye ne-biompatifa ye-peek
PEEK is a specialty engineering plastic with excellent properties, and its main characteristics include high strength, high wear resistance, high temperature resistance, radiation resistance, good chemical stability, and good biocompatibility. I-Biomifatifayiling yisalathiso esiphambili sokufaneleka komxholo wokusetyenziswa kwezixhobo zonyango kunye nokufakelwa, kwaye i-peek igqwesa ngokumalunga noku. Inokubakho ngokusesikweni emzimbeni womntu ixesha elide ngaphandle kokukhulisa amagorha okanye ityhefu yetyhefu, ngenxa yoko ithathelwa ingqalelo njengezixhobo ezifanelekileyo zePolymer.
Okwesibini, izibonelelo zoncedo lwe-3D
1. Imveliso eyenziwe ngokwezifiso: Ingcali ephambili yetekhnoloji ye-3D yokuphucula ukufezekisa imveliso eyenzelwe wena kunye nemveliso. Kwicandelo lezonyango, imeko nganye yomzimba kunye neemfuno zawo zahlukile, kwaye iindlela zemveliso ze-batch zemveli zihlala zisilela ukuhlangabezana nalo mfuneko yabucala. Nge-3D eprintwe, ogqirha banokuthi bayile kwaye benze izixhobo zonyango ezinobubele kunye ne-itherplants ngokusekwe kwimfuno ye-anatomy yesigulana kunye neemfuno zotyando.
2. Ukuchaneka kunye nokuntsonkotha: Itekhnoloji yokuprinta ye-3D yenza ukuba i-PRECT ifezekise imveliso yezakhiwo ezichanekileyo nezintsonkothileyo. Inqaku eliphezulu le-Peek liyivumela ukuba ifakwe kwi-FDM yeeTekhnoloji yiTekhnoloji ye-FDM, ekhokelela kwizixhobo zonyango kunye neendlela zokufakwa kwizakhiwo zangaphakathi ezibandayo kunye nezinto ezikhoyo.
3. Ukukhawulezisa inkqubo yoqhaqho kunye nokuBuyiswa: I-3D ye-3D iprinta izixhobo kunye nokufakwa zinokuyilwa kwaye zenziwa kwangaphambili ngokwesicwangciso sotyando, kwaye sinciphise inkqubo yokubuyisela kwimeko yesiqhelo ye izigulana.
Okwesithathu, imizekelo yomzekelo we-3D eprintayo kwicandelo lezonyango
I-1. Iiplagi ze-Orthopenic: Ngenxa yokuba iipropathi zoomatshini be-Peek zikufuphi nethambo lomntu kwaye zisetyenziselwa ukufakelwa kwe-biopic ezifana nezixhobo ze-crest kunye nezixhobo ezidibeneyo. Ngetekhnoloji ye-3D yokuprinta, ubume kunye nobungakanani bunokwenziwa ngokwezifiso ngokwemeko yesigulana, ukuphucula izinga lempumelelo lotyando kunye nokuthuthuzela ngomonde.
I-2. I-Cardiac Stents: Iziqwenga zentliziyo ze-perek zine-biomiatifa elungileyo kunye ne-X-ray ingenela ngoogqirha ukuba babeke esweni isikhundla kunye nenqanaba le-Stent ngokucinga emva kotyando. Itekhnoloji yokuprinta i-3D ingenza i-Peek Cardediac Stents ineemilo zejometri ezintsonkothileyo kunye nezakhiwo zentsholongwane ukuze zilingane neempawu ze-anatomicals.
I-3. Iimodeli zoNyango kunye neziKhokelo: Kwiinkqubo ezinzima zotyando, ukusetyenziswa kweemodeli ze-3D ezishicilelweyo kunye nezikhokelo zinganceda ucwangciso lwaphambi kokusebenza kunye nokuthathwa kokusebenza, ukuphucula utyando.
Okwesine, ukujonga kwixesha elizayo
Nangona ukusetyenziswa kwe-3D eprintweyo kwi-Deverity yezonyango iphumelele iziphumo ezimangalisayo, amandla ayo akude ukuba afakwe ngokupheleleyo. Ngokuqhubela phambili phambili kophando oluqhubekayo lwezinto ezibonakalayo kunye nophuhliso kunye nokuphuhlisa ubugcisa, sinokulindela ukuba le mikhwa ilandelayo yophuhliso:
1. Uphando kunye nophuhliso lwezinto ezintsha ze-Peek: ngokubutha i-Peek kunye nezinye izinto zebhayiloji okanye ezisebenzayo, njengokukhuthaza ukuchithelwa kweseli, njengokukhuliswa kweseli, njalo njalo.
2. Yandisa ukuchaneka kunye nesantya seTekhnoloji ye-3D: Itekhnoloji ye-3D ye-3D kulindeleke ukuba ifezekise isisombululo esiphakamileyo kwaye siprintwe ngokukhawuleza, simiselwe ngokufanelekileyo kwaye sichanekile.
3. Ukwandisa ubungakanani bezicelo zeklinikhi: ngophando olunzulu kwi-bimomatives kunye neepropathi zoomatshini ze-PERK, kulindeleke ukuba i-3D iprintwe isetyenziswe kwiindawo zonyango, ezinjengee-iurosurgery, i-denthalmology njalo.
Ukuqukumbela, i-3D iprinta i-Peek inamandla amakhulu kwicandelo lezonyango, elingenakukhuthaza kuphela ukuveliswa kwemveliso yezakhono kunye nezezisikweni kwezixhobo zonyango kunye nokufakwa kweziphumo zonyango kunye nokomeleza iziphumo zonyango kwaye ziphucule iziphumo zonyango. Ngeenzame ezingagungqiyo zabaphandi kunye nokuyilwa kwetekhnoloji, sinesizathu sokukholelwa ukuba i-PERVE ye-3D iya kudlala indima ebaluleke ngakumbi kwixesha lezonyango, elizisa izibonelelo ezingakumbi kwimpilo yabantu!
